Camelpox Virus in Western Kazakhstan: Assessment of the Role of Local Fauna as Reservoirs of Infection.

This article investigates the role of local fauna in Western Kazakhstan as potential reservoirs of the camelpox virus (CMLV). The study emphasizes analyzing possible sources and transmission pathways of the virus using polymerase chain reaction (PCR) and serological methods, including virus neutralization tests and enzyme-linked immunosorbent assays (ELISA). Samples were collected from both young and adult camels, as well as rodents, ticks and blood-sucking insects in the Mangystau and Atyrau regions.

Assessment of Peste des Petits Ruminants Antibodies in Vaccinated Pregnant Ewes of Kazakh Breed Fine-Fleeced and Determination of the Decreasing Trend of Maternal Immunity in Their Lambs.

In this article, we first assessed peste des petits ruminants (PPR) antibodies in vaccinated pregnant ewes of Kazakh breed fine-fleeced immunized with the PPR vaccine and the duration of maternal immunity in their lambs. Ewes in the last trimester of pregnancy and gestation were immunized with a vaccine from the Nigeria 75/1 strain of the PPR virus (PPRV) produced by the Research Institute of Biological Safety Problems (RIBSP), Kazakhstan. Serum samples from lambs born from vaccinated and unvaccinated ewes were collected a week after birth and at intervals of 7 days for 18 weeks after birth.

Biochemical Analysis of the Blood of Cattle after Vaccination with a Heterologous Vaccine for Lumpy Skin Disease.

We studied the biochemical parameters of the blood of cattle after immunization against lumpy skin disease with a vaccine made from an attenuated heterologous goat pox virus (strain G-LKV). Blood samples were obtained from animals on days 7, 14, and 21 after vaccination. The vaccine did not affect biochemical parameters of the blood.

[Adaptation of the sheep pox virus (Poxviridae: ) to African green monkey kidney cell line and evaluation of its immunobiological properties].

Introduction: Outbreaks of infectious diseases seriously hinder the preservation and increase of the number of small ruminants. Such infections include sheep pox virus (SPPV). According to the OIE data of 2021, SPP outbreaks were registered in countries such as Turkey, Israel, China, Maldives, Mongolia, Thailand, Russia, Algeria, Kenya, and in 2019 in Mangistau and Atyrau regions.

[Determination of the optimal immunizing dose of heterologous goat pox virus vaccine (Poxviridae: Chordopoxvirinae: Capripoxvirus) against lumpy skin disease].

Introduction: Lumpy skin disease (LSD), sheep pox and goat pox are dangerous diseases of domestic ruminants. Representatives of the genus of capripoxviruses are antigenically similar and can be used as a vaccine for three infections, as in the case of representatives of the genus of orthopoxviruses, which includes viruses of smallpox, monkeypox, and cowpox, that all belong to a single family Poxviridae.

Materials And Methods: In this study, the vaccine strain G20-LKV of the goat pox virus and the virulent strain RIBSP2019/K of the LSD virus were used.

Duration of Protective Immunity in Sheep Vaccinated with a Combined Vaccine against Peste des Petits Ruminants and Sheep Pox.

In this study, the ability of the combined vaccine against peste des petits ruminants (PPR) (Nigeria strain 75/1) and sheep pox (SPP) (NISKhI strain) to form a protective immune response for 12 months in Kazakh breed fine-fleeced sheep aged 6-12 months was demonstrated. The duration of the protective immunity of immunized sheep from PPR and from SPP was evaluated using a serum neutralization test (SNT), followed by testing of the resistance of vaccinated sheep to infection with the field strain Kentau-7 of the PPRV and the virulent strain A of the SPPV. The PPR antibody response was additionally measured by c-ELISA.
